Once again stratified tuning left me speechless. I have to say the customer services is just awesome. I always had the feeling that I was under good hands. I have never had a problem and don't think I ever will. Alex takes every tune personally and I have to say it shows it. Every time I had a question alex answered it with complete detail so I could understand it. I do consider alex a wizard in the mazdaspeed world even if he doesn't believe it. I will be coming back when I get more upgrades. Thanx alex. 100% awesome.

Once I started working with Stratified, specifically Stan, It was easy to see their dedication to the customers, providing the best possible power and drivability for our vehicles. Stan went through extraordinary efforts during our tuning process to make sure I was getting the best and safest power outputs at all times. During the tuning process I was always informed and educated of what was going on, why we made changes what we’d work on correcting in the next steps and how it’ll impact the vehicle.

Stratified did wonders to my speed3 and I couldn’t be happier with the result and the process that created it. I highly recommend Stratified for any tuning needs.

Dealing with Stratified (Alejandro Buse) has been a great experience. I have learned a lot about my car and its capabilities/wants/needs and am excited to put my newly empowered ride to the test. I track regularly and just finished my tune and am 3 weeks out from seeing what this tune will do for my times.

The turn around time was prompt every time. I sent logs and would have new maps within a day, sometimes 2; but never longer.

I asked questions, some good ones, some dumb ones and was never given anything but a respectful informative response.

I would give these guys more that 5 stars if it were an option. My car, under its current build, has entered beast mode thanks to Stratified and Alejandro.

Sincerely,
Struggling for traction in 3rd =p

Well the custom tune or "product" is really the experience of these guys, Mike in my case. Very helpful, took on board my queries, gave advice and proceeded the tune in a safe manner. When you give someone almost free rein to play with your car it could be a bit daunting but not in this case! Also being involved in the process, as in doing the actual logs makes it a better experience in my view. Highly recommend anyone who is thinking of doing this to get in touch with them. Very satisfied customer cheers!

I was very happy about the support of Alex and also the contructive work together with Alejandro. I used an stage I map from cobb, but there is a big difference between the cobb stage I map and the custom tune of Stratified. I'M satisfied with the results! Thanks for everything!BR G

This is by far the best thing you could do for your car!!! Custom Tune is the only way to go. My car runs smoother and faster than ever. Worth every penny IMO. Alejandro was my tuner and I couldn't of asked for a better experience. These guys are on top of and know there stuff when it comes to tuning!! Thanks again Alejandro and Stratified Auto
